Run time programing

[Sid2286]

hi,

I was just trying to work on programing during runtime.
Like I want to give the values to the controller through keypad.

Does this involves EEPROM into picture??

I want to ask the user for the variable for further processing.

Don't help me with the code, I would like to work on it. But just give me a hint to how to proceed.


Regards,
sid

It is not really clear as to what you are asking.
Generally a running program can receive information that will change the running process by taking data from an input pin or pins and placing it in volatile memory (RAM) and having the running program read the RAM and react. This data is lost when power is lost. The input could be received into ram and then transferred to non-volatile such as EEPROM or the program flash itself. Look at write/read eeprom and write/read program memory for examples.

Yes I was looking for exactly what you said.

Thanks
